ʻenehana hoʻopaʻa māmā
No ka mea, pono e pale ʻia ka nani a me ka pale ʻana o ka substrate coating ponoʻī, ʻoi aku ka maikaʻi o nā mea ʻino i ke kaiapuni e like me ka wela, ka oxygen, ka wai, a me ka māmā. ʻOiai ʻaʻole komo pololei ka hapa nui o nā polymers i nā kukuna UV, aia nā mea hoʻoheheʻe a pau a ʻoi aʻe a liʻiliʻi paha i ka UV -mea e hoʻoulu ai i ka resin peroxidation. Hiki i ke kukui Ultraviolet (mai ka lā) ke ho'ēmi i ka maikaʻi o ka pena. Hiki ke like ka hopena o ke kukui artificial. Hiki i nā kukuna UV ʻino ke uhaki i nā paʻa kemika i nā polymers. Hoʻohaʻahaʻa kēia i ka resin e alakaʻi ana i nā loli i ka pena e like me ka ʻeleʻele, ka ʻulaʻula, ka ʻulaʻula, ka melemele, nā ʻōpala, ka nalowale o nā waiwai kino a me ka pale. Kapa ʻia kēia kaʻina hana kemika he photooxidation. UV -LED Photooxidation Kaʻina Photooxidation he ʻelua hana nui. ʻO ka mua ke kaʻina hana o ka photodissociation, kahi kaʻina hana paʻakikī i hana ʻia ma nā ʻanuʻu he nui, me ke kukui ultraviolet, a laila wehe i ke kī i nā molekala e hana ana i nā radical manuahi. ʻO ke kaʻina hana ʻelua, ʻo ia ke kaʻina oxidation, kahi i hana ʻia ai nā radical manuahi i ka wā photolysis e hana me ka oxygen e hana i nā radical superoxide. Aia nā ʻanuʻu 5 i ke kaʻina photooxidation. Ma ka wehewehe ʻana aʻe, hōʻike ʻo R i kahi ʻāpana o ka resin pena i hiki ke hoʻokahe ʻia i benzophenone. Aia nā ʻanuʻu 5 i ke kaʻina photooxidation. Ma ka wehewehe ʻana aʻe, hōʻike ʻo R i kahi ʻāpana o ka resin pena i hiki ke hoʻokahe ʻia i benzophenone. Aia nā ʻanuʻu 5 i ke kaʻina photooxidation. Ma ka wehewehe ʻana aʻe, hōʻike ʻo R i kahi ʻāpana o ka resin pena i hiki ke hoʻokahe ʻia i benzophenone.
